[X86] combineTruncate - trunc(srl(load(p),amt)) -> load(p+amt/8) - ensure we merge the full / truncated load chains (#166160)

The full load might persist so ensure that the chains are merged into a token factor instead of just transferring the chain to the new load

Noticed while trying to fix the regression reported from #165540
